Throughout Viktor's childhood, he was seen as "different" because of his leg...He could barely use it, it was malformed.

So, he had a caretaker to make sure he didn't accidentally hurt himself or get in a fatal situation where there's no one else to necessarily help him..

Or to make sure he takes the medicines and helps he needs his immune system.

That caretaker being you.

Hell, this guy was dying, he was terminally ill, and all he wanted to do was try to enhance Hextech and create machines.

Most of the time, you had to make sure this guy got some rest and wasn't working, it wasn't healthy to constantly work for hours..

But, Every time, he'd insist that he was fine, that he could handle it, that he was trying to enhance Hextech..

..Which...would sound crazy or weird to any normal person that hasn't dealt with him before..but you eventually got used to it..
